Seven Common Problems of Vacuum Packaging Machine

Jul. 03, 2020

Vacuum packaging technology originated in the 1940s. In 1950, polyester and polyethylene plastic films were successfully used in vacuum packaging. Since then, vacuum packaging has developed rapidly.

Vacuum Packaging Machine is divided into an internal pumping vacuum packaging machines and external pumping vacuum packaging machines, as well as the automatic vacuum packaging machine we often say. In these three series, there are several types, such as internal pumping vacuum packaging machine is divided into a single-chamber vacuum packaging machine, a double-chamber vacuum packaging machine, a vertical cabinet vacuum packaging machine, and a continuous rolling vacuum packaging machine.

The vacuum packaging machine is suitable for vacuuming, inflating, and fitting packaging machines for various foods, meat products, seafood, fruits and vegetables, pickles, cooled meat, medical products, hardware components, etc. But the following 7 problems often occur, what is the reason? Packing machine manufacturer to introduce you.

Vacuum Packaging Machine


Low vacuum

Reasons and measures:

1. The pump oil is polluted, too little or too thin, and the vacuum pump needs to be cleaned or replaced with a new vacuum pump oil

2. The pumping time is too short, extend the pumping time;

3. The suction filter is blocked, and the exhaust filter is cleaned or replaced;

4. If there is an air leak, turn off the power after evacuation, and check the electromagnetic valve, pipe joint, vacuum pump suction valve and the surrounding gasket of the studio for air leaks.


loud noise

Reasons and measures:

1. The vacuum pump coupling is worn or broken, and the vacuum pump needs to be replaced;

2. The exhaust filter is blocked or the installation position is not correct. Clean or replace the exhaust filter and install it correctly;

3. Check the solenoid valve for leaks and eliminate the leaks.


Vacuum pump fume

Reasons and measures:

1. The suction filter is clogged or polluted, and the exhaust filter needs to be cleaned or replaced;

2. The pump oil is polluted and replaced with new oil; the oil return valve is blocked and the oil return valve is cleaned.


No heating

Reasons and measures:

1. The heating bar is burnt out, replace the heating bar;

2. The heating time relay burns out, replace the time relay;

3. The heating wire is burnt out, replace the heating wire, and install firmly;

4. Poor contact of the heating temperature band switch, repair or replacement;

5. The AC contractor that controls heating is not reset, repaired (to blow off foreign objects with airflow) or replaced;

6. The heating transformer is broken, replace it.


Heating does not stop

Reasons and measures:

1. Poor contact or burnout of the heating time relay, adjust the time relay to contact or replace with the socket;

2. Control heating AC contactor not to reset, repair or replace.


Vacuum pump fuel injection

Reasons and measures:

1. The O-ring of the suction valve falls off, unplug the vacuum tube on the pump nozzle, remove the suction nozzle, take out the compression spring and the suction valve, gently stretch the O-ring several times, and re-insert it into the groove, Just install it again;

2. The rotary blade is worn, replace the rotary blade.


Vacuum pump oil leakage

Reasons and measures:

1. The oil return valve is blocked, remove the oil return valve for cleaning;

2. The oil window is loose. After draining the oil, remove the oil window and wrap it with raw material tape or thin plastic film.
